Polylactic acid (PLA) is a biodegradable polymer that widely used in medical devices, drug delivery systems, fibers for packaging containers and textiles. However, given interactions between the materials contact with it affect its applications, important to study adsorption diffusion properties. The capacity of different polylactic particles regarding additives, e.g. essential oils (Thymus vul...

The paper describes an optimised strategy to measure the porosity in natural fibre composites. Particular emphasis is placed on thermoformed flax fibres reinforced poly-lactic acid (FFRPLA) laminates. Six different methods were evaluated and compared: gravitometry ethanol water, scanning electron microscopy (SEM), computed tomography (CT) scanning, optical microscope measurements inverse identi...

Cellulose, dissolved in ionic liquids (IL), can be used successfully the processing of thermoplastics. To recover liquid while maintaining thermoplastic properties, other spacers than IL might introduced into cellulose network. Such blend materials have been prepared before by solution blending as reported literature. In this study, preparation and investigation polylactic acid (PLA) blends usi...

Gelatin-hydroxyapatite-polylactic acid (PLA) nanocomposites were synthesized using five different formulations. The nanocomposites were loaded with ibuprofen and the amount of drug in the carriers was determined. X-ray diffraction (XRD) analysis was conducted before and after drug loading to ensure the presence of ibuprofen on the nanocomposites. Drug delivery was evaluated in phosphate buffere...
